Title: Filter bag
Inventor: SCHMIERER ERICH
IPC: A47L9/14
Filed: 1989-02-23
Abstract: A filter bag, which is used in dust-extracting appliances for receiving the dust and is of closed design with the exception of an inlet opening, has a multi-layer bag wall made of air-permeable material. If the bag wall is at least three-layered, the pore size of the layers decreasing towards the outside, a greater sealing and greater filling capacity of the filter bag than hitherto are achieved. Furthermore, one layer of the multi-layer bag wall can consist of an electrostatically chargeable material, which consolidates very fine dust. Furthermore, the filter bag can have a germicidal layer, which consists of material which kills allergens or is provided with such a material or medium. The air escaping from the filter bag is then free from such allergens.

Title: Bubble-proof liq. flowmeter independent of pipe orientation - enables gas bubbles to by=pass oscillation channel in which frequency is measured pref. by electronic sampling
Inventor: JENSEN NIELS DUE
IPC: G01F1/32
Filed: 1989-08-29
Abstract: Inlet and outlet couplings (2,3) are joined by a flow tube (4) to which a circular oscillation channel (7) is connected at a point (8) between the fluidic gate nozzle (10) and a separator (12).  Frequency of the oscillatory current is sampled (14)  while the liq. flows always in the same direction (A). The pressure difference between inlet and outlet planes (16,17) drives the flow so that small bubbles (15) move rapidly along a path (a) to the top of the housing (1) if the inlet and outlet levels are the same.  Otherwise bubbles pass unhindered to the outlet (3). USE/ADVANTAGE - In a fluidic-gate type flowmeter.  Very accurate measurement unperturbed by gas bubbles is achieved regardless of whether the device is installed in a horizontal or a vertical section of pipe.

Title: Grinding rounded edge on cylindrical workpiece - inclining grinding wheel axis to workpiece axis
IPC: B24B9/00
Filed: 1989-08-29
Abstract: The end face (1) of a cylindrical workpiece (2) is ground by a cup-shaped grinding wheel (5) which has a flat face at its open end. The grinding operation consists of two phases. In the first phase the workpiece (2) is rotated about its own axis (3) as it is pressed against the grinding wheel (5) which rotates about a parallel axis (4). In the second phase the grinding wheel axis (4) is inclined at an angle (11) to the workpiece axis (3). At the same time the grinding wheel (5) is positoned so that its rim intersects the edge of the workpiece in two places. Grinding the workpiece in this way produces a rounded edge (10) of an approximately constant radius. USE - Grinding of cylindrical workpieces.
